  • Microbicidal Compositions Including Activated Nitrogenous Compound and 1,4-Bis(Bromoacetoxy)-2-Butene, and Methods Of Using The Same
    Publication number: 20100173018
    Abstract: Microbicidal compositions for aqueous systems are provided that include (a) a nitrogenous compound activated by an oxidant or an enzyme and (b) 1,4-bis(bromoacetoxy)-2-butene (BBAB). The components are present in a combined amount synergistically effective to control the growth of at least one microorganism. Methods for controlling the growth of microorganisms in aqueous systems with the compositions are also provided.

  • Compositions and Methods To Control the Growth Of Microorganisms In Aqueous Systems
    Publication number: 20080241247
    Abstract: Compositions and methods for killing, preventing, or inhibiting the growth of microorganisms in an aqueous system or other systems are provided. The compositions can include at least one first cross-linkable polymer, at least one second cross-linkable polymer, and at least one cross-linking agent, wherein the water solubilities of each cross-linking polymer are different, such as by 10% to 100%. The compositions can further include at least one biocidal component. The compositions can be formulated to slowly release the biocidal component and/or the cross-linkable polymer, or rapidly release the biocidal component and slowly release the cross-linkable polymer. The compositions can be used to control algae.

  • Haloperoxidase treatment to control algae
    Publication number: 20070197388
    Abstract: A method for killing, preventing, or inhibiting the growth of algae in an aqueous system is provided by providing a haloperoxidase, and hydrogen peroxide or a peroxide source to a chlorinated water system under conditions in which the haloperoxidase, peroxide from the hydrogen peroxide or peroxide source, and chloride ions or chloroamines in the chlorinated water system interact to provide an antialgal agent.
